We are traveling by auto and are halfway between home and our destination. My husband has been having frequent tooth problems and infection. He is currently on 500 mg of Amoxicillin and has been taking Advil for quite a while. He has been feeling generally run down but felt instantly better after starting the Amox on Friday. Beginning yesterday he began having dry mouth, voracious thirst, and has had to stop to urinate every 90 minutes or so. The urge is so strong he can't wait for an exit sometimes. The volume of urine is VERY large. Last night he began feeling poorly again and was anxious and acting strange, and after taking the Amox suddenly began shaking with chills and fever. He still has fever this morning.
